This is interesting:
Some of the high-res
guidance is beginning to come around to the idea of showing
convective development trailing back westward along a cold front
with a weakening capping inversion into central VT/NH as soon as
early overnight; but the timing and coverage of this activity still
is pretty scattershot across the high-res suite. This could
ultimately end up being a nowcast situation, but given this trend I
couldn`t really justify NBM`s nil PoPs. Opted for up to 30% PoP
along the MA/NH/VT border between 4-7 AM Wed, then slowly sagging
southward through the day. If any storms develop, they would
likely become strong to potentially severe quickly given the
degree of instability aloft and pretty strong NW mid-level
winds, with frequent lightning, hail and strong straight line
winds all possible, potentially early in the day as well. Low
confidence but potentially higher impact if storms can
materialize.
